Resideo VU444A1155 Actuator
The Resideo VU444A1155 is a heavy-duty 120V fan coil actuator designed for high-cycle commercial HVAC applications. This two-position SPST actuator features a robust spring return mechanism, ensuring positive shut-off in the event of power loss. Engineering specifications include a 15-second opening time and a rapid 6-second spring return timing over a 45-degree stroke. Built for durability in demanding mechanical rooms, the unit utilizes a nickel-plated motor, a stainless steel case, and an aluminum cover to resist corrosion. This model is engineered specifically for seamless integration with 2-way normally open VU52 series valve bodies or 3-way VU series valve bodies, providing reliable hydronic control in terminal units. The 6-inch electrical leads allow for straightforward wiring into existing 120Vac control circuits. When replacing older Honeywell fan coil actuators, this component ensures consistent flow regulation and system pressure management without the need for extensive piping modifications.
Technical Benefits for Contractors
- Compatibility: Direct fit for VU52 normally open and VU series 3-way valve bodies, reducing truck stock requirements.
- Mechanical Durability: The nickel-plated motor and stainless steel housing prevent binding and environmental wear in high-humidity fan coil units.
- Fail-Safe Operation: The reliable mechanical spring return ensures the valve returns to its safe position during power interruptions.
- Rapid Cycle Response: Optimized timing prevents water hammer while maintaining precise temperature control in commercial zones.
Common Installation Questions
Is the VU444A1155 compatible with both 2-way and 3-way valves?
Yes, this actuator is designed to work with VU52 series 2-way normally open valves and the standard VU series 3-way valve bodies commonly found in hydronic systems.
Can I use this actuator in a 24V control system?
No, the VU444A1155 is a dedicated 120Vac actuator. Applying 24V will result in failure to actuate, while higher voltages will damage the nickel-plated motor.
What is the purpose of the manual lever on the housing?
The manual lever allows technicians to manually open the valve for system filling, venting, or emergency operation, and it automatically disengages when power is restored.
